Norplex-Micarta RTB320Z Phenolic Linen Laminate Tube, NEMA LE
Categories:	Polymer; Thermoset; Phenolic
Material Notes:	RTB320Z is similar to RTB320X being composed of an extra-fine weave woven cotton fabric combined with a phenolic resin system. RTB320Z tubes have higher densities (minimum allowable specific gravity is 1.30) resulting in enhanced precise machining characteristics and are expected to give longer life in wear applications. Typical uses include retainers for ball-bearings. RTB320Z also complies with MIL-I-24768/13, Type FBE, ASTM D709 Type II Grade LE and Federal Specification WW-L-2887.
